Subject: [PATCH 4.4 09/32] net: ieee802154: stop dump llsec keys for monitors
Date: Mon, 26 Apr 2021 09:29:07 +0200 [thread overview]
Message-ID: <20210426072816.905115470@linuxfoundation.org> (raw)
In-Reply-To: <20210426072816.574319312@linuxfoundation.org>
From: Alexander Aring <aahringo@redhat.com>
[ Upstream commit fb3c5cdf88cd504ef11d59e8d656f4bc896c6922 ]
This patch stops dumping llsec keys for monitors which we don't support
yet. Otherwise we will access llsec mib which isn't initialized for
monitors.
